Complete Plastic Manufacturing – All Under One Roof

Unlike many suppliers, Protoshape offers the full process in-house:
  • Plastic part design & Design for Manufacturability (DFM)
  • Precision toolmaking using aluminium and steel
  • Injection moulding for low, medium, and high volumes
Having everything under one roof means faster decisions, fewer delays, and better results for our customers.​

Plastic Part Design

Designing Parts That Work in the Real World
Good plastic part design is critical to successful tooling and injection moulding. Our designs are informed by decades of hands-on toolmaking and moulding experience, ensuring parts are manufacturable, cost-effective, and reliable.
We use full CAD design tools to:
  • Develop new products from concept
  • Optimise existing parts for injection moulding
  • Apply Design for Manufacturability (DFM) from the outset

​Toolmaking

Precision Injection Mould Toolmaking in Scotland
Our in-house toolmaking capability allows us to manufacture and maintain high-quality injection moulding tools, including:
  • Full steel tools for high-volume production
  • Bolster tools for rapid, cost-effective manufacturing
  • Insert plates for prototyping and low-volume runs
  • Family tools producing multiple parts in one mould
We machine tools using Haas CNC machines and EDM spark erosion, working with P20 tool steel and tool-grade aluminium. Tool modifications, repairs, and maintenance are fast and efficient because everything stays in-house.

Injection Moulding

Low to High-Volume Injection Moulding Services
Injection moulding is ideal for repeatable, high-quality plastic parts. At Protoshape, we mould:
  • Low-volume prototypes and pilot runs
  • Medium-volume production
  • High-volume, multi-cavity production
We work with a wide range of materials, including:
  • Commodity plastics (PP, HDPE)
  • Engineering plastics (ABS, Nylon, Acetal)
  • Recycled and eco-friendly plastics
Our bolster and insert plate systems allow customers to get parts made faster and at lower cost, without sacrificing quality.
